IMPORTANT INFORMATION BEFORE INITIATION

Please read carefully before starting the device! The consumption sensor VA 400 measures the flow velocity (calorimatric principle) in the middle of the pipe. Please observe mounting instruction and inlet section = 15 x inner diameter and outlet section = 5 x inner diameter. The final values of the measuring ranges are as follows: VA 400 standard version 92.7 m/s, please take the flow rates from the tables on pages 10-11 VA 400 max. version 185 m/s, please take the flow rates from the tables on pages 12-13 VA 400 high speed version 224 m/s, please take the flow rates from the tables on pages 14-15 1. VA 400 with display with 4… 20 mA analogue and pulse output Please enter inner diameter of the pipe! Values indicated in the display: Actual value in m³/h, m³/min etc. Counter in m³ resp. l as well as pulse output, 1 pulse per m³ resp. l are calculated according to the set diameter. Please take the analogue value for flow rate 4… 20 mA from the tables on pages 10 to 15. 4 mA always corresponds with the starting value 0 m³/h, 0 m³/min. The final value 20 mA can be taken from the tables on pages 10 to 15. Example VA 400 Standard: 1" with inner diameter 25.0 mm, 4 mA = 0 m³/h and 20 mA = 122.2 m³/h 2" with inner diameter 53.1 mm, 4 mA = 0 m³/h und 20 mA = 600.0 m³/h 2. VA 400 without Display with 4… 20 mA analogue output (without pulse output) No adjustments are necessary at the consumption sensor. The respective final values for the flow rate can be taken from the tables on the pages 10 to 15. 4 mA is always set as scaling value 0. 20 mA is the final value . Example VA 400 Standard: 1" with inner diameter 25.0 mm, 4 mA = 0 m³/h and 20 mA = 122.2 m³/h 2" with inner diameter 53.1 mm, 4 mA = 0 m³/h und 20 mA = 600.0 m³/h

Please read carefully before starting the device! Warning: Do not exceed the pressure range of 50. From 10 bar we recommend to use the high-pressure protection for a safe installation and removal. Observe the measuring ranges of the sensor! Overheating destroys the sensor. Observe the admissible storage and transporation temperature as well as the permitted operating temperature (e. g. protect the instrument from direct insolation). Always observe the direction of flow when positioning the sensor! The safety ring at the sensor head must always remain undamaged and sit correctly in the destined slot. The screwed fixture must be pressure tight. The adapter sleeve must be tightened with a torque of 20 to 30 Nm. It is absolutely necessary to avoid condensation on the sensor element or water drops in the measuring air as they may cause faulty . The values of the inlet and outlet sections must not fall below the specified minimum values as this causes increased deviations in the measuring results. The manufacturer cannot be held liable for any damage which occurs as a result of non-observance or non-compliance with these instructions. Should the device be tampered with in any matter other than a procedure which is described and specified in the manu-al, the warranty is cancelled and the manufacturer is exempt from liability. The device is destined exclusively for the described application. CS Instruments GmbH offers no guarantee for the suitability for any other purpose and is not liable for errors which may have slipped into this operation manual. CS Instru-ments GmbH is also not liable for consequential damage resulting from the delivery, ca-pability or use of this device. We offer you to take back the instruments of the instruments family VA 400 which you would like to dispose of. Adjustments and calibrations should only be carried out by qualified employees from the measurement and control technology branch.

SAFETY INSTRUCTIONS

Please read carefully before starting the device! The consumption sensor VA 400 works according to the calorimetric measuring principle.

Burnable gases If this consumption sensor is used for measurement of burnable gases (e. g. natural gas) we explicitly point out that the sensor has no DVGW (= German Technical Association for Gas and Water) admission, however, it can be used for natural gas. A DVGW admission is not mandatory.

The consumption sensor VA 400 corresponds with the latest state of technology and can generally be used for burnable and non-burnable gases. For the use in e. g. natural gas the sensor will be calibrated in natural gas. The calibrati-on protocol (inspection certificate) is included in the scope of delivery. The area outside the pipe (environment of the sensor) is not allowed to be an explosive area.

The installation has to be done by authorized expert staff.

INSTRUMENTS DESCRIPTION VA 400 is a consumption sensor for consumption measurement of compressed air and gases. The version with integrated display indicates the actual consumption e. g. in m³/h and m³. Special features: - Option integrated display - units freely selectable in the display - consumption counter resettable - inner pipe diameter adjustable - Depth scale for accurate installation - Usable from tube diameter 1/2" (DN 15) - Easy installation under pressure - 4...20 mA analogue output for m³/h resp. m³/min - Pulse output for m³ Programming via Service Software SFA 300. - Analogue output 4...20 mA scalable - Switching between m³/h, m³/min, ft/min, l/min, l/s, cfm, m/s - Reading out the service data

Determining the point of installation In order to maintain the accuracy stipulated in the data sheets, the sensor must be inserted in the centre of a straight pipe section with an undisturbed flow progression. An undisturbed flow progression is achieved if the sections in front of the sensor (inlet) and behind the sensor (outlet) are sufficiently long, absolutely straight and without any obstruc-tions such as edges, seams, curves etc. Careful attention must be paid to the design of the outlet section as obstructions can cause counter-flow turbulence as well as turbulence in the direction of the flow.

L = Length of the entire measuring section L1 = Length of inlet section L2 = Length of outlet section D = Diameter of measuring section

The respective minimum values required are indicated here. If it is not possible to observe the stipulated equalising sections, considerable deviations in measuring results must be expected. Sensor installation

Hint for the installation with ball valve: Ball valve R 1/2“, DN 15 Passage ball valve minimum Ø15 mm

Consider the flow direction which should match with the arrows at the connector head.

Measure from here to the tube center Read the insertion position here

The sensor head must be placed in the centre of the pipe. Therefore the probe shaft has a scale. To determine the right position measure the length from the marked position to the centre of the tube. The probe then will be inserted up to this measure and then tightened up.

ASSEMBLY INSTRUCTIONS

Assembly instructions Safety information must be observed. Assembly is carried out by inserting the connection thread (1/2“ thread, SW 27) into the connection piece. The sensor is then inserted to the required immersion depth and aligned according to the direction of air flow. A depth scale engraved on the probe tube, a flow alignment arrow and an aligning device will be of help to you. Once the sensor has been aligned, the adapter sleeve must be tightened with the stipulated torque (SW 17). Attention: Alignment of the sensor must not be modified when tightening the connection thread and adapter sleeve. In this case please check the immersion depth and alignment again and correct if necessary. The angular deviation should not be greater than ± 2° in re-lation to the ideal position as otherwise the measuring accuracy will decrease. Commissioning The valid measuring range and delivery configuration are programmed by the manufacturer on the basis of the user’s specifications. The stationary flow and air consumption measuring devices from the VA 400/ DS 300 se-ries function according to the “plug and play” principle. The device is ready for operation as soon as the power supply is connected. .

Measuring ranges depending from the inner diameter of the pipe

MEASURING RANGES HIGH SPEED

The sensor VA 400 - high speed version with or without display, has a maximum measuring range of 224.0 m/sec. The flow rate is programmed to: Inner diameter: 53.1 mm This corresponds with an analogue output 4… 20 mA of 0… 1450.06 m³/h 0… 24.17 m³/min 0… 24167.64 l/min 0…402.79 l/sec 0… 224.0 m/sec. In case of the version with display the inner diameter 25.00 has to be set first if the sensor is used in other pipes, e. g. 1", 25 mm. The analogue output for 1" can be taken from the table below: 4… 20 mA = 0… 295.30 m³/h 0... 4.92 m³/min 0… 4921.62 l/min 0… 82.03 l/sec 0… 224.0 m/sec. In case of the version with display please adjust the respective inner diameter (see page 21).

Maximum velocities of VA 400 for different gases and reference standards

Please note: The consumption sensor VA 400 corresponds with the latest state of technology and can generally be used for burnable and non-burnable gases. If this consumption sensor is used for measurement of burnable gases (e. g. natural gas) we explicitly point out that the sensor has no DVGW admission, however, it can be used for burnable gases. A DVGW admission is not mandatory.

For the use in e. g. natural gas the sensor will be calibrated in natural gas. The calibration protocol (inspection certificate) is included in the scope of delivery.

The area outside the pipe (environment of the sensor) is not allowed to be an explosive area.

Pulse output: 1 pulse per m³ (factory setting) With the option display VA 400 or in case of connection to a multifunction measuring instrument DS 300 the pulse output to litre, kg, cf is set via the setting of the consumption unit litre/min, kg/h, cfm. Active pulse to connector plug A (PIN 5)

In case of the version VA 400 without display the pulse is an active signal (not galvanically isolated) Pulse +P = +VB (12...30 VDC), max. current I = 10 mA, to connector plug A. If VA 400 is connected to a multifunction measuring instrument DS 300 DS 300 will convert the active pulse signal into a galvanically isolated pulse. Pulse diagram please see page 18. Galvanically isolated pulse to plug B (PIN 4 and PIN 5)

In case of the version VA 400 with display there is a galvanically isolated pulse available on connector plug B (PIN 4 and 5) in addition to the connector plug A (PIN 5). An isolated contact is clo-sed for the duration of the pulse (semi-conductor relay galvanically isolated by optocoupler). Maximum switching capacity: 30 VDC, 20 mA Pulse diagrams please see page 18.

SERVICE INFORMATION

Maintenance The sensor head should be checked regularly for dirt and cleaned if necessary. Should dirt, dust or oil accumulate on the sensor element, a deviation will occur in the measuring value. An annual check is recommended. Should the compressed air be heavily soiled this interval must be shortened. Cleaning of the sensor head The sensor head can be cleaned by carefully moving it to and fro in warm water with a small amount of washing-up liquid. Avoid physical intervention on the sensor (e. g. using a sponge or brush). If soiling cannot be removed, service and maintenance must be carried out by the manufacturer. Re-calibration If no customer specifications are given then we recommend to carry out calibration every 12 months. For this purpose the sensor must be sent to the manufacturer. Spare parts and repair For reasons of measuring accuracy spare parts are not available. If parts are faulty they must be sent to the supplier for repair. If the measuring device is used in important company installations we recommend to keep a spare measuring system ready. Calibration certificates Calibration certificates are issued by the manufacturer on request. This is a fee-paying service. Precision is tested with DKD (= German calibration authority) certificated volume flow meters.

21 V5-02-2010

DISPLAY FUNCTION

Display VA 400 can display up to 3 measured values. This are volumetric flow/mass flow, velocity and total consumption. For better reading only one measured value is displayed. The measured val-ues are toggled during normal operation mode every 3 seconds. The following changes can be made : - Diameter - Unit volume flow (m³/min, m³/h, l/min, l/s, kg/s, kg/min, kg/h, cfm) - Display of measured value (volume flow, velocity, total consumption) - Zero consumption - Display contrast - Display turnable by 180 ° Settings ex works: - Volume flow in m³/h ( If the sensor is calibrated for reference DIN 1343, the unit is Nm³/h. This unit is only adjustable in the factory or with the CS Service Software.) - Total consumption in m³ - Diameter If not ordered by customer, the diameter will be preset to 53.1 mm.
